WDG Insitu Probe

The WDG Insitu flue gas oxygen probe differs from all other oxygen insitu probes. The unique inner/outer probe design facilitates removal of cell, heater and thermocouple assembly through the probe head. Once the inner probe assembly is removed, the outer probe support pipe allows straight run access to insitu filter for cleaning with compressed air. The inner probe assembly also exposes the reference side of the zirconium cell to ambient air eliminating the need for instrument air utilities at the probe mounting location.
